Merge tag 'dt-for-v3.18' into omap-for-v3.18/tmp-merge

Changes for .dts files for omaps for v3.18 merge window:

- Updates for gta04 to add gta04a3 model
- Add support for Tehnexion TAO3530 boards
- Regulator names for beaglebone
- Pinctrl related updates for omap5, dra7 and am437
- Model name fix for sbc-t54
- Enable mailbox for various omaps

Conflicts:
arch/arm/mach-omap2/board-generic.c

Merge tag 'mailbox-for-v3.18' into omap-for-v3.18/tmp-merge

Mailbox related changes for omaps to get it to work with
device tree.

Merge tag 'intc-for-v3.18' into omap-for-v3.18/tmp-merge

Interrupt code related clean-up for omap2 and 3 to make
it ready to move to drivers/irqchip. Note that this series
does not yet move the interrupt code to drivers, that will
be posted separately as a follow-up series.

Note that this branch has a dependency to patches both
in fixes-v3.18-not-urgent and soc-for-v3.18 and is based on
a merge. Without doing the merge, off-idle would not work
properly for git bisect.

Merge tag 'soc-for-v3.18' into omap-for-v3.18/tmp-merge

SoC related changes for omaps for v3.18 merge window:

- PM changes to make the code easier to use on newer SoCs
- PM changes for newer SoCs suspend and resume and wake-up events
- Minor clean-up to remove dead Kconfig options

Note that these have a dependency to the fixes-v3.18-not-urgent
tag and is based on a commit in that series.

Merge tag 'fixes-v3.18-not-urgent' into omap-for-v3.18/tmp-merge

Fixes for omaps that were not considered urgent enough
for the -rc cycle:

- Fixes for .dts files to differentiate panda and beaglebone versions
- Powerdomain fixes from Nishant Menon mostly for newer omaps
- Fixes for __initconst and of_device_ids const usage

Merge tag 'fixes-v3.17-rc4' into omap-for-v3.18/tmp-merge

Few regression fixes for omaps for the -rc cycle:

- Fix for omap_l3_noc bus code
- Serial console fix for cm-t53
- NAND timings fix for dra7-evm

arm: omap: intc: switch over to linear irq domain

ARM: omap2: make arrays containing machine compatible strings const

The definition

static const char *omap3_boards_compat[] __initconst = {

defines a changable array of constant strings. That is you must not do:

*omap3_boards_compat[0] = 'f';

but

omap3_boards_compat[0] = "another string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

mailbox/omap: add support for parsing dt devices

Logic has been added to the OMAP2+ mailbox code to parse the
mailbox dt nodes and construct the different sub-mailboxes
associated with the instance. The DT representation of the
sub-mailbox devices is different from legacy platform data
representation to allow flexibility of interrupt configuration
between Tx and Rx fifos (to also possibly allow simplex devices
in the future). The DT representation gathers similar information
that was being passed previously through the platform data, except
for the interrupt type information, which is gathered through driver
compatible match data.

The non-DT support has to be maintained for now to not break
OMAP3 legacy boot, and the legacy-style code will be cleaned
up once OMAP3 is also converted to DT-boot only.

ARM: dts: OMAP5: switch to compatible pinctrl

Now that ti,omap5-padconf is available, switch over to that compatible
property. Retain pinctrl-single for legacy support.

While at it, mark pinctrl as interrupt controller so that it can be
